Durgalith is a company that has been developing, producing and selling ALSAN systems and products since 1972. In 1996 the company, along with its entire workforce and infrastructure, was integrated in SOPREMA.
The merger of the two companies – and consequently of their mutual expertise – led to new, innovative and patented products.
It was especially the combination of bitumen and polyurethane and the resultant raw material, BITU-PU resin, that really revolutionised several applications in the flat-roof area. ALSAN FLASHING is a product that represents a milestone in terms of application options and quality when it comes to waterproofing upstands and edges, as well as solutions for details.
The ALSAN RS product group, a range based on polymethyl methacrylates, is another Soprema innovation that is conquering the waterproofing and surfacing market.
